Abstract

La présente invention concerne un procédé pour régénérer un catalyseur d'élimination de NO¿x?. Ce procédé permet de rétablir facilement l'activité catalytique d'un catalyseur d'élimination de NO¿x? usé et assure une grande efficacité de fonctionnement. Cette invention concerne particulièrement un procédé pour régénérer un catalyseur d'élimination de NO¿x? (14) d'un agent dénitrifiant de gaz d'échappement. Ce procédé consiste à immerger le catalyseur dans une eau de régénération à température ordinaire (31) qui ne contient sensiblement pas de chlore ni de composants nettoyants, puis à le retirer et à le déshydrater.
